I am trying to get radio button like this..

But I am getting like this
You can achieve desired layout in two ways
Via removing standard appearance using CSS appearance and applying custom appearance. Unfortunately this was doesn't work in IE for Desktop (but works in IE for Windows Phone). Demo:
input[type="radio"] {
/* remove standard background appearance */
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
/* create custom radiobutton appearance */
display: inline-block;
width: 25px;
height: 25px;
padding: 6px;
/* background-color only for content */
background-clip: content-box;
border: 2px solid #bbb;
background-color: #e7e6e7;
border-radius: 50%;
}
/* appearance for checked radiobutton */
input[type="radio"]:checked {
background-color: #93e026;
}
/* optional styles, I'm using this for centering radiobuttons */
.flex {
display: flex;
align-items: center;
}
Via hiding radiobutton and setting custom radiobutton appearance to label's pseudoselector. By the way no need for absolute positioning here. Demo:
*,
*:before,
*:after {
box-sizing: border-box;
}
input[type="radio"] {
display: none;
}
input[type="radio"] + label:before {
content: "";
/* create custom radiobutton appearance */
display: inline-block;
width: 25px;
height: 25px;
padding: 6px;
margin-right: 3px;
/* background-color only for content */
background-clip: content-box;
border: 2px solid #bbb;
background-color: #e7e6e7;
border-radius: 50%;
}
/* appearance for checked radiobutton */
input[type="radio"]:checked + label:before {
background-color: #93e026;
}
/* optional styles, I'm using this for centering radiobuttons */
label {
display: flex;
align-items: center;
}
